As shown in fig. 1, the sofa hinge clamp spring assembling machine comprises a frame, a lifting mechanism and a rotating clamp mechanism.

The lifting mechanism comprises a sliding rail 100 arranged along the height direction of the rack, a sliding table in sliding fit with the sliding rail 100, and a first cylinder 110 for driving the sliding table to lift; the rotating and clamping mechanism comprises a motor 120 arranged on the sliding table and a clamping tongue 130 connected with a main shaft of the motor 120, the lower end of the clamping tongue 130 comprises a shifting rod 140 eccentrically arranged with the main shaft, and the shifting rod 140 is used for shifting the clamp spring to rotate to a mounting position.

When the sofa hinge and the clamp spring are put under the rotating and clamping mechanism during working, the lifting mechanism drives the sliding table to lift along the sliding rail 100 in the height direction of the rack through the first air cylinder 110, the rotating and clamping mechanism is lowered to the working height, the motor 120 of the rotating and clamping mechanism rotates for a certain angle to drive the deflector rod 140 at the lower end of the clamping tongue 130, and the deflector rod 140 and the main shaft of the motor 120 are eccentrically arranged, so that the deflector rod 140 can toggle the clamp spring hook to rotate to the position of the fixed column for installation; after the installation is completed, the motor 120 rotates in the opposite direction, and after the shift lever 140 is separated from the clamp spring, the lifting mechanism drives the rotating and clamping mechanism to ascend to wait for the next working cycle.

In some embodiments of the utility model, the frame includes a bottom plate 150, a top plate 160 parallel to the bottom plate 150, and a riser 170 connecting the bottom plate 150 and the top plate 160. The rack is reliable in structure and provides reasonable mounting positions for the lifting mechanism and the rotary clamping mechanism.

Specifically, the first cylinder 110 is mounted on the top surface of the top plate 160, the slide rail 100 is disposed on the vertical plate 170, and the top plate 160 is provided with a through hole for receiving the piston rod of the first cylinder 110 therethrough. The first cylinder 110 and the slide rail 100 are reliably arranged in this way, and stable operation is ensured.

In addition, a mounting plate 180 is provided on the base plate 150, and the mounting plate 180 is provided with a counter bore 190 for receiving the head of a bolt of a sofa hinge. The mounting plate 180 is provided with a counter bore 190 to play a positioning role, so that the sofa hinge and a clamp spring on the sofa hinge are placed at a correct mounting position.
